Which of the following characteristics of uranium make it useful for the method of radiometric dating?

Uranium is a member of the actinide series.
Uranium is a solid.
Uranium is radioactive.
Uranium is found in nature.

The uranium-235 to lead-207 decay series is marked by a half-life of 704 million years. These differing rates of decay help make uranium-lead dating one of the most reliable methods of radiometric dating because they provide two different decay clocks.

Explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
